Would the Conservatives' ban on four-day weeks for council staff improve efficiency?

Some UK councils, like South Cambridgeshire District Council, trialled a four-day week with 80% hours for full pay, reporting improvements in 21 of 24 service areas, faster call responses, quicker planning applications, and reduced agency costs. The Conservative Party proposes banning this practice nationwide, arguing taxpayers deserve full-time services for full-time pay to ensure value for money. Debate centres on whether such schemes boost productivity through better staff wellbeing or undermine it by reducing available working days.
